Couldn't find an elka rear suspension for a blaster except for a brand new one any I'm not paying that much $. I did find however a 400ex elka for cheap. I got Ken occonner bushings and the we're SUPER snug but with some persuasion went in and bolted up nicely. The bottom however seems sloppy. Also, i never had to drill anything lIke in ken's video. I'm obviously missing something... what is it???
